Merck, D188700-100G, N,N′-Dimethylthiourea

N,N′-Dimethylthiourea, also known as 1,3-Dimethylisothiourea, is commonly used in organic reactions to synthesize N-containing compounds such as N-acyl-substituted 1,1-diaminoethylenes, amidines, ureas, and thioureas. It also acts as a nucleophilic catalyst in the bromination of alcohols using N-bromosuccinimide (NBS), during the conversion to the corresponding bromides.
